The high probability of particle–bubble contact, and subsequent short residence times (five to ten seconds in the downcomer, allows for a much more compact column design than conventional column flotation cells (see Figure 1). The fine nature of the bubbles (0.3 to 0.5 mm in diameter) gives them enhanced carrying capabilities for fine mineral particles.

the introduction of column flotation. Flotation columns differ radically from conventional mechanical flotation units both in design and operating philosophy. This has been a cause of the reluctance to test these units industrially since their invention (in Canada) in the mid-60's by Boutin and Tremblay.
A reliable scale-up procedure for column flotation must address three important areas of column design, ie column geometry, sparging system and wash water distribution network. The column geometry is dictated by the maximum froth carrying capacity (which determines column diameter) and the bubble-particle attachment rate and particle retention time (which determines column length).
Flotation is used for fine coal beneficiation, where operating parameters must be optimised for individual coal (Kaylani et al., 2005). A flotation column is used in the cleaning stages of flotation circuits due to a better selectivity in relation to conventional mechanical flotation cells. The design of flotation column

A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column to overflow into a concentrate launder, while the

2. Model Formulation of Column Flotation 2.1. Model Description Column flotation utilizes the principle of countercurrent flow, in which air is introduced into the column at the bottom through a sparger or in the form of externally generated bubbles and rises through the downward-flowing slurry that contains mineral, locked, and gangue
The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
flotation at laboratory scale, an investigation was carried, in order to design a (laboratory) column flotation cell at the Chair of Mineral Processing, which had to be based on the findings of an intense literature study. The final cell design was manufactured in co-operation with an Austrian provider for construction in plastics.
